Nice one !

Frame set landed in Australia super fast ! About a week . Shipping cost was way less than half some other brands are asking . Frame was packed well and arrived unmarked ! Finish is top tier . Bikes still a rolling shell so I can’t confirm how it performs but it sure does look good ! Cant wait to rip some skids on Aussie gravel ! Thanks SBC

Pics of frame with 45c tires

45c tires fit perfect in the front but rear is very close but still will work

Good solid frame

Rear dropouts, good paint, all of the braze-ons and appointments make this a great versatile sled for any one speed build.

Perfect for gravel build

Built up with State 6061 wheelset, 32c gravel tires and compact drop bars. Just finished 334 mile Great Allegheny Passage and C&O Canal trail from Pittsburgh to DC. Perfect bike frame and setup for the trip. Comfortable ride, relatively light setup, no issues. Plenty of braze-ons if I wanted to add even more accessories for the next trip. Only issue was that the rear dropout was slightly bent when I received the frame. State told me they would send out a new frame same day to replace it but I was able to adjust it so didn't need to take them up on the offer. This is the fourth or fifth time I've ordered something from State and the customer service has always been great.
